Title:
METHOD FOR DRAWING IRIDIUM OF IRIDIUM ALLOY WIRE
Document Type and Number:
Japanese Patent JP3647029
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method by which a high-quality flawless wire is formed efficiently by drawing a wire made of iridium or an iridium alloy.
SOLUTION: In the method by which drawing is performed by heating the wire made of iridium or iridium alloy and making it pass through a die, the working is performed with a specified working rate per pass of the die and by heating the wire at the inlet of the die. As the heating method of the wire, it is preferable to arrange one electrode of a pair of the electrodes separately from the die on the inlet side of the die and to arrange the other electrode proximately to the die on the outlet side of the die and to energize the electrodes by bringing the pair of electrodes into contact with the wire.
